scaling"?

Yes, except pdfTeX is a little bit subtler.

First, font expansion can be used after the lines have been justified
(\pdfadjustspacing=1), in which case TeX builds the paragraph without
expansion and applies it in a cosmetic fashion afterward, so lines look
better, or it can be used in the justification process
